Question

Which sentence best describes mass movement?

Answer 1

The right option is; C. The downhill flow of soil and rock resulting from gravity

Mass movement is the bulk movements of soil, sand, regolith and rock debris down slopes in response to the force of gravity. Mass movement usually occurs along hillsides and mountains and it can occur very fast or slowly. Falls, slides, creeps and flows are the four main classes of mass movements and they are classified based on the movement of the rock and sediments along with the amount of the water content.

Answer 2

here is why... B and D don't make any sense and are not relevant to the question and A really doesnt go along with the question either.
